We propose developing a wide area situation awareness (WASA) application for android mobile phones.

Social network analysis is a powerful method for making sense of an increasingly interconnected world. Developing social network analysis tools requires datasets with which to test them, but sharing datasets is problematic because of privacy issues. Initial attempts to anonymize network datasets proved ineffective due to de-anonymization attacks that leveraged publically available information to i ...

The purpose of this topic is to develop a pump that can pump two-phase, liquid and vapor mixtures of common refrigerants and heat transfer fluids, without oil lubrication. The challenges of pumping in this regime are well known: Two-phase, liquid-vapor refrigerant mixtures are a mixture of saturated liquid and saturated vapor, by definition meaning that there is zero net positive suction head. M ...

Longwave infrared (LWIR, 8-12µm) focal plane arrays (FPAs) play an important role in hyperspectral chemical and biological (CB) sensing and spectral imaging. Existing thermal detectors are unable to meet the high sensitivity and fast response requirements of many hyperspectral chemical and biological sensing applications. FPAs based on photon excited electron generation process can fulfill the sp ...

Magnolia proposes to develop and demonstrate small unit cell APD array with high gain for high resolution imaging in the ultraviolet (UV) band. We will use MOCVD process to demonstrate GaN/AlGaN based APD arrays on lattice matched substrates with very low dark current and high avalanche gain. Models will be developed to understand characteristics of small pixel size UV detectors and mechanisms for ...

LongWave Photonics proposes a terahertz quantum-cascade laser based swept-source optical coherence tomography (THz SS-OCT) system for single-sided, 3D, nondestructive evaluation (NDE) of non-conductive materials. The THz SS-OCT system uses a frequency tunable QCL array to generate an interferometric signal between a reference mirror, and a sample. An algorithm is used to transform this signal in ...

Leveraging on Agiltron industry leading development of optical systems and the PI experience with FTIR spectrometer design, we propose to develop a new class of compact monolithic Fourier-transform spectrometers for the long-wave (7.5-13 m) infrared optical range. The proposed solution is based on creating a spatial interferogram with a pair of a calomel Wollaston prisms and digitizing it with an ...

Biological agents pose high threats, because they are invisible and odorless and a relatively small amount can infect a large population when released in a densely populated area. For the same reasons, assuring safety after cleaning decontaminated sites can be challenging. Currently available technologies require considerable labor, and results typically cannot be obtained before 24 V 48 hours up ...

ElectroChem proposes a Phase II program to advance its Phase I effort, to develop a conductive water removal membrane to enable passive, high current density PEMFC operation. Very good progress was demonstrated by the two approaches investigated: 1) Construct a carbon-based composite, higher bubble point membrane; 2) convert a polymer-based water removal membrane to a conductive membrane (both ...

NASA's Vision for Space Exploration advocates a return to the moon and involves a pl an of using the moon as a base of for missions to other planets. Early return missions to the moon will involve lunar exploration with robotic spacecrafts with instrumental payloads for scientific measurements of lunar surface features such as rocks, soil, and minerals. These instrument payloads will be helpf ...
